Injection Mold Tooling
Achieve precise, custom aluminum and steel injection molds built to your exact requirements. Perfect for high-volume production, our molds meet tight tolerances down to 0.02 mm (0.0008 in) and include complimentary mold flow analysis to ensure optimal performance.
Overmolding
Overmolding combines multiple materials by molding plastic over a base component (substrate), resulting in a single, robust part with enhanced durability and customization options in texture and color.
Insert Molding
Insert molding is a specialized injection molding method that embeds metal or other components into molded plastic parts by placing inserts into the mold before injection, reducing or eliminating the need for secondary fasteners.
China-Based Expansive Manufacturing Network
With its own manufacturing facilities and a carefully selected partner network in China, ZONZE enables rapid turnaround and scalable production of custom metal and plastic components—delivering consistent quality and dependable results across every project.
